Hooray! It might seem strange to 'hooray' over something like this, but I say HOORAY!
For so many of your earlier posts on this thread, you were struggling with setting boundaries and taking steps that would force your mom to start taking responsibility for herself.
I am so happy that you did what you did. I think your 'gut' reaction (like someone else said) was your heart talking and I'm thrilled that you listened to it. As I've said before, "advice is what we ask for when we already know the answer but don't want to admit it".
Personally, I feel like you did the right thing - not just for your mom, but for yourself and your family. I support you.
